just want to add, utsource's 2SK216 are fakes as well. The ones they send you are different from the ones in their pictures. Avoid avoid avoid!
Quote:I'm sorry if you felt that we were being territorial. But seriously, these aren't impression threads. It's better to have a central repertoire of information on these builds. It'll be less likely for someone to miss a key piece of information this way, and KG wouldn't have to answer the same questions a thousand times. Besides, the existing threads already have a wealth of information in it. I fail to see why we need new threads for them. If KG feels like it's better to open a thread here, he will.
That pretty much sums up what I thought.
people should really make specific threads for builds and DIY. It makes the info a lot more accessible to others who want to do the same stax related things. and removes the need to trawl through pages and pages of unrelated posts.
A long time ago, perhaps, mods should've just made people make separate threads (or maybe separate electrostatics subforum) instead of it all (ok not all but a lot of it) ending in the 2x 1000p threads.
Oh dear, Little Diode took you to the cleaners on those 2SC3381. Ouch!
Elsewhere, they can be had for <$2ea, unless they too have sold out.
If you bought your ebay sand from a source in Israel, they are most likely fakes.
One type that has caused others grief was the 2SK216.
Read up on it in the T2 thread over there...
What deadlylover said, "test, test, test"!
Please dont feel bad.
Many of us have had to spend extra to fund this pursuit to build the T2.
What is important is to keep the junk parts out of the build.
In the past this has proven to create much grief during the test phase, bringing seasoned engineers to their knees.
I for one do not want to encounter the same problems that others have dealt with in the recent past.
Troubleshooting a complicated build like this is no walk in the park.
[size=11.0pt]Are you sure about no copyrights? [/size]
[size=11.0pt]Power supply is different design from the original T2 PS. The amplifier section has at least a new topology from Dr. Gilmore, not to mention case thermal management (perhaps industrial design?). [/size]
[size=11.0pt]Sure he has released BOM, schematics (perhaps patents over the amplifier section schematic are no longer enforceable) and PCB layouts as companies can do reverse engineering anyway, isn’t it? [/size]
[size=11.0pt]As far as I am concerned, the original designer and Dr. Gilmore gave permission for[/size] [size=11.0pt]DIY only[/size][size=11.0pt]. [/size]
[size=11.0pt]IMHO, I still think there is some extent of intellectual property protection regarding such amplifier. [/size]
[size=11.0pt]No company is authorized to replicate the innovative part of it without Dr. Gilmore authorization, although very few companies would want to do it. Stax itself won’t do it again. Is there a relevant market for it? [/size]
[size=11.0pt]The serious companies able to do small runs of expensive amplifiers would ask for a license anyway.[/size]
I can find no copyrights on DIY T2 anywhere including US Copyright Office.
Note that I am NOT a company and am NOT making DIY T2's for sale, I am building one for myself. I don't know what prompted your remarks regarding intellectual property. I am not posting schematics, BOM's PCB designs.... etc. Don't know where you got any such ideas.

So, well.. BHSE vs ordinary KGSS has been described nearby, but I'd also like to know how does KGSSHV relate to BHSE in terms of sound? And also T2 vs BHSE. I suspect though that very few people acutally had all of them..
2. < I fail to see why we need new threads for them.> There no threads on Head-fi.org for the T2.
...and there is a very good reason for that.
There is not a whole lot of difference between the two amps and both are excellent.
